This 1.5ct lab-grown heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436070364 or 436070364. Listed at 5 retailers as of October 26, 2026, with prices from €2,962 to €5,588, a €2,626 spread on the same certified stone. MOH London lists it at €5,588. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
